A probability distribution is an equation that?
Associates a particulare probability of occurrence with each outcome in the sample space.
What re the three criteria needed for something to be a probability distribution?
A probability distribution must have a well defined domain - that is, the set of possible outcomes.For each possible outcome, there must be a non-negative value associated - the probability of that outcome.The sum of the probabilities, over all possible outcomes, must be 1.
What is an expected outcome in probability?
The expected outcome is the sum of (each possible occurrence times the probability of that occurrence). For example, the expected outcome of rolling one die is: 1 * 1/6 + 2 * 1/6 + 3 * 1/6 + 4 * 1/6 + 5 * 1/6 + 6 * 1/6 = 3.5.
What is the probability of getting a sum of 4 when the two number cubes are rolled?
There are 3 combinations - (1, 3), (2, 2), (3, 1) - that will result in a sum of four. Using fair d6 dice, there are 36 possible combinations - 6 on each die, 6 x 6 = 36. Thus there is a 3/36 = 1/12 = 0.0833.. = 8.3% probability.
What is a probability distribution?
A probability distribution is a function that describes the probability of obtaining a certain outcome where the outcomes are not equally likely. There is a fixed probability of getting each outcome, but the probabilities are not necessarily equal. For example, roll 2 dice, there are 36 equally likely outcomes with a probability of each occurring being 1/36. However if we look at the sum of the numbers, there is only one outcome that gives a sum of 2 (1&1) , so P(sum 2) = 1/36, but six outcomes that give the sum of 7 (1&6, 2&5, 3&4, 4&3, 5&2, 6&1), so P(sum 7) = 6/36 = 1/6. Probability distributions can be tabulated, or there are functions that can be used to calculate the probabilities of getting each outcome.

What is the probability of each possible outcome when you roll two die in 36 possible combinations?
It is 1/36 since each outcome is equally likely.
Explain probability distribution?
A probability distribution describes the likelihood of different outcomes in a random experiment. It shows the possible values of a random variable along with the probability of each value occurring. Different probability distributions (such as uniform, normal, and binomial) are used to model various types of random events.
What does uniform probability mean in math?
Uniform probability can refer to a discrete probability distribution for which each outcome has the same probability. For a continuous distribution, it requires that the probability of the outcome is directly proportional to the range of values in the desired outcome (compared to the total range).

What the ethical issues in probability distribution?
Probability distribution is when all the possible outcomes of a random variation are gathered together and the probability of each outcome is figured out. There are several ethical issues with this one being that it is not always accurate information that is gathered.
What is an expected outcome in probability?
The expected outcome is the sum of (each possible occurrence times the probability of that occurrence). For example, the expected outcome of rolling one die is: 1 * 1/6 + 2 * 1/6 + 3 * 1/6 + 4 * 1/6 + 5 * 1/6 + 6 * 1/6 = 3.5.
